USB: remove interface parameter of usb_reset_composite_device
From the current implementation of usb_reset_composite_device function, the iface parameter is no longer useful. This function doesn't do something special for the iface usb_interface,compared with other interfaces in the usb_device. So remove the parameter and fix the related caller.
